On HPE Gen9 platforms and HPE Gen10/Gen10 Plus platforms, when the Smart Array Controller is configured in the non-default Balanced power mode, the Smart Storage Administrator (SSA) and Array Diagnostic Utility (ADU) may report informational messages similar to the following: SSA: "846 A reboot will enhance performance for HPE Smart Array P408i-p SR Gen10 in slot x" OR "845 A reboot will enable additional power saving for HPE Smart Array P408i-P Gen10 in slot x" Where "x" is the PCIe slot number. ADU report (Device Summary): "A reboot will enable additional power savings" OR "A reboot will enhance the controller's performance" This issue occurs when the Smart Array controller is configured with "Balanced" Power Mode. The following are examples of configuration changes and a subsequent system reboot, which may cause this issue: Adding additional drive(s) to the existing configuration. Removing drive(s) from the existing configuration. Configuring unassigned drive(s) as Logical Drives. Note: The default Power Mode setting is Maximum performance.
In the above scenario, any HPE Gen9 platforms configured with any of the following controllers running firmware version 7.0 (or earlier): HPE Smart Array P244br Controller HPE Smart Array P246br Controller HPE Smart Array P440 Controller HPE Smart Array P441 Controller HPE Smart Array P741m Controller HPE Smart Array P840 Controller HPE Smart Array P841 Controller In the above scenario, any HPE Gen10/Gen10 Plus platforms configured with any of the following controllers running firmware version 2.03 (or earlier): HPE Smart Array E208e-p SR Gen10 (8 External Lanes/No Cache) 12G SAS PCIe Plug-in Controller HPE Smart Array E208i-a SR Gen10 (8 Internal Lanes/No Cache) 12G SAS Modular Controller HPE Smart Array E208i-a SR Gen10 (8 Internal Lanes/No Cache) 12G SAS Modular LH Controller HPE Smart Array E208i-c SR Gen10 (8 Internal Lanes/No Cache) 12G SAS Modular Controller HPE Smart Array E208i-p SR Gen10 (8 Internal Lanes/No Cache) 12G SAS PCIe Plug-in Controller HPE Smart Array P204i-b SR Gen10 (4 Internal Lanes/1GB Cache) 12G SAS Modular Controller HPE Smart Array P204i-c SR Gen10 (4 Internal Lanes/1GB Cache) 12G SAS Modular Controller HPE Smart Array P408e-p SR Gen10 (8 External Lanes/4GB Cache) 12G SAS PCIe Plug-in Controller HPE Smart Array P408i-a SR Gen10 (8 Internal Lanes/2GB Cache) 12G SAS Modular Controller HPE Smart Array P408i-a SR Gen10 (8 Internal Lanes/2GB Cache) 12G SAS Modular LH Controller HPE Smart Array P408i-c SR Gen10 (8 Internal Lanes/2GB Cache) 12G SAS Modular Controller HPE Smart Array P408i-p SR Gen10 (8 Internal Lanes/2GB Cache) 12G SAS PCIe Plug-in Controller HPE Smart Array P408e-m SR Gen10 (8 External Lanes/2GB Cache) 12G SAS Mezzanine Controller HPE Smart Array P416ie-m SR Gen10 (8 Int 8 Ext Lanes/2GB Cache) 12G SAS Mezzanine Controller HPE Smart Array P816i-a SR Gen10 (16 Int Lanes/4GB Cache/SmartCache) 12G SAS Modular LH Controller HPE Smart Array P816i-a SR Gen10 (16 Internal Lanes/4GB Cache/SmartCache) 12G SAS Modular Controller
This issue has been resolved in HPE Smart Array SR Gen10 Controller firmware version 3.00 (or later). This firmware version can be found at the following links: Windows (x64) Linux (x64) ESXi If this issue has occurred on HPE Smart Array Gen9 Controllers, use the SSA to determine if the message remains after the initial system reboot. If the issue remains, perform another system reboot.
